Synthesis of Graphene Quantum Dot Magnesium Hydroxide Nanocomposites and Investigation of Their Antioxidant and Antimicrobial Activities
Curr Microbiol. 2023 Apr 12;80(5):181. doi: 10.1007/s00284-023-03286-0.ABSTRACTIn this paper, we synthesized graphene quantum dots magnesium hydroxide nanocomposites (GQDs/Mg(OH)2). The synthesized nanocomposites were characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and Malvern Zetasizer. The antimicrobial and antioxidant properties of the obtained GQDs/Mg(OH)2 nanocomposites were investigated. GQDs/Mg(OH)2 nanocomposites have MIC values of 15.625 μg/mL against fungi (C. metapsilosis and C. par...

Mechanistic Insight into the role of Vitamin D and Zinc in Modulating Immunity Against COVID-19: A View from an Immunological Standpoint
Biol Trace Elem Res. 2023 Mar 9:1-15. doi: 10.1007/s12011-023-03620-4. Online ahead of print.ABSTRACTThe pathophysiology of coronavirus disease-19 (COVID-19) is characterized by worsened inflammation because of weakened immunity, causing the infiltration of immune cells, followed by necrosis. Consequently, these pathophysiological changes may lead to a life-threatening decline in perfusion due to hyperplasia of the lungs, instigating severe pneumonia, and causing fatalities. Additionally, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause mortality due to viral septic shock, resulting from unr...

Hypomagnesemia is associated with increased mortality in the short-term but not the long-term in community-acquired pneumonia patients with type 2 diabetes
CONCLUSIONS: Hypomagnesemia is common in CAP inpatients with T2DM. Moreover, in these patients, hypomagnesemia at admission is associated with increased mortality in the short-term but not the long-term.PMID:36354240 | DOI:10.1684/mrh.2022.0499
